Edithb - I have a bit of arthritis in both hands and started using Dava picks. For me, they have a really positive grip. I pick up mine at my local music store but here's the website https://www.davapick.com/ .
By the way - I love The Bellamy Brothers. I've seen them live a few times and they sounded every bit as good live as on record.
Happy New Year,
